Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX540 HS and the Epson R-D1? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Canon SX540 and the Epson R-D1 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

Compare SX540 versus R-D1 top
Comparison SX540 or R-D1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Epson R-D1 is notably larger (28 percent) than the Canon SX540. In this context, it is worth noting that neither the SX540 nor the R-D1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX540 has a lens built in, whereas the R-D1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the R-D1 and their specifications in the Leica M Lens Catalog.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX540 was launched at a lower price than the R-D1, despite having a lens built in. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX540 features a 1/2.3-inch sensor and the Epson R-D1 an APS-C sensor. The sensor area in the R-D1 is 1221 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX540 has a native 4:3 aspect ratio, while the one in the R-D1 offers a 3:2 aspect.

Canon SX540 and Epson R-D1 sensor measures

Despite having a smaller sensor, the Canon SX540 offers a higher resolution of 20.2 megapixels, compared with 6 MP of the Epson R-D1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 7.85μm for the R-D1). However, it should be noted that the SX540 is much more recent (by 11 years and 9 months) than the R-D1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX540 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX540 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX540 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Epson R-D1 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.

The Canon PowerShot SX540 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Epson R-D1 are ISO 200 to ISO 1600 (no boost).

SX540 versus R-D1 MP

Many modern cameras cannot only take still pictures, but also record videos. The SX540 indeed provides movie recording capabilities, while the R-D1 does not. The highest resolution format that the SX540 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the R-D1 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX540 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SX540 and Epson R-D1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The SX540 has one, while the R-D1 does not. While the built-in flash of the SX540 is not very powerful, it can at times be useful as a fill-in light.

The SX540 writes its imaging data to SDXC cards, while the R-D1 uses SDHC cards. The SX540 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the R-D1 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot SX540 HS and Epson R-D1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX540 offers wifi support, while the R-D1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Epson R-D1 (unlike the SX540) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The SX540 is a recent model that features in the current product line-up of Canon. In contrast, the R-D1 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the R-D1 from Epson. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Epson websites.

Review summary

So how do things add up? Is there a clear favorite between the Canon SX540 and the Epson R-D1? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Canon PowerShot SX540 HS:

  • More detail: Offers more megapixels (20.2 vs 6MP) with a 79% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Broader imaging potential: Can record not only still images but also 1080/60p movies.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (461k vs 235k dots).
  • Faster burst: Shoots at higher frequency (5.9 vs 1 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens built-in, whereas the R-D1 requires a separate lens.
  • More compact: Is smaller (120x82mm vs 142x89mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the R-D1).
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 11 years and 9 months of technical progress since the R-D1 launch.

ilogo

Advantages of the Epson R-D1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • More flexible: Takes interchangeable lenses and can thus be used with different optics.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been around for much longer (launched in March 2004).

If the number of relative strengths (bullet points above) is taken as a guide, the SX540 is the clear winner of the match-up (16 : 10 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

SX540 16:10 R-D1

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX540 or the R-D1. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
